What parents need to know

Ease of play

This app is easy to play. Kids drag the words "greater" or "lesser" onto the center of the screen to complete the equation. They then create a bar graph representing each fraction compared side-by-side so that they can visually see if they were correct.

Engagement, Approach, Support

Engagement

This basic educational app works best for kids who are struggling to understand fractions by showing visual feedback.

Learning Approach

Visual explanation of fractions is valuable, but the app provides no further information for kids to monitor performance or progress, and single activity doesn't allow for much depth.

Support

The simple interface doesn't need much explanation, but no help features are offered just in case you need guidance.

Kids can learn to compare two fractions, judging which one is greater and which is less. They learn to visually represent fractions using a divided bar to help them make sense of fractions and compare them, even when they have different denominators. Oh No Fractions! offers a simple way for kids to think about and practice fractions.

What's it about?

Kids are given two fractions, one on each side of the screen. They must decide if the one on the left is GREATER than or LESS than the second fraction on the right. Players drag their chosen word, greater or less, into place and choose "I'M SURE" to check their answer. They'll see if their answer was "correct" or "wrong" and then be able to "Prove it!" The prove it screen shows each fraction on a bar divided into equal spaces based on the denominator. Kids drag over the boxes to fill in the numerator for each and then see the fractions compared side-by-side on the graph. They can also just tap to reveal the solution.

Is it any good?

QUALITY

The design is elegant, and the visual demonstration of comparing fractions helps kids to makes sense of comparing fractions. Kids are told if their answer was "correct" or "wrong" and then given an opportunity to see visually why this is so by using the feature called "Prove it." The "Prove it" feature puts kids in charge of creating each fraction on a visual bar graph, so that they can compare the two fractions. This visual explanation is a powerful way to help kids to understand comparative fractions. While there is no record of total correct and incorrect answers, and the app offers no data about which particular fractions may have caused difficulties, the point of this free app is to provide kids with a digital tool to help them to understand. The sound effects are minimal -- a bleep for correct answers and a bonk for wrong answers -- but that audio can be turned off. Kids can set the max denominator for up to 99.

Families can talk about...

Point out fractions to kids as you encounter them in everyday life -- "1/4 of our family ordered chicken for dinner" or "1/3 of your homework is finished."

Show kids different ways to compare fractions using everyday objects -- "Our pizza has eight slices. We each had two slices or 2/8 of the pizza. That's the same as 1/4."
